Glycolysis |
Glycolysis is a series of steps in which a glucose molecule is broken down into two molecules of pyruvate as the chemical bonds and glucose are broken electrons and hydrogen ions are picked up by NAD+ forming NADH glucose is oxidized and NAD+ is reduced Annette output of two ATP molecules are also produced in glycolysis for every loucos molecule process but most of the energy released by the breakdown of glucose is carried by the electrons attached to NADH |

Citric acid cycle |
The pyruvate molecules are modified as they enter the mitochondrion releasing carbon dioxide. the altered molecules enter a series of reactions called the citric acid cycle. more carbon dioxide is released as the citric acid cycle completes the oxidation of glucose. 2 atps are formed per glucose but most of the energy released by the oxidation of glucose is carried by NADH and fadh2 |

Oxidative phosphorylation |
Almost all of the ATP produce by cellular respiration is banked in the final phase- oxidative phosphorylation. The NADH and FADH2 molecules produced in glycolysis and the citric acid cycle donate there electrons to the electron transport chain. At the end of the chain oxygen exerts a strong pull on the electron and combines with them and hydrogen Ions (protons) to form water. The electron transport chain converts chemical Energy of moving electrons to a form that can be used to drive oxidative phosphorylation which produces about 34 ATP molecules for each glucose molecule consumed. |
